Abstract

Es wird ein Seil beschrieben, welches insbesondere als Tragseil für Seilbahnen geeignet ist. Das Seil umfasst einen Kern (31) und mehrere den Kern umgebenden Aussenstränge, welche beispielsweise aus mehreren Drähten (32.1...32.6, 34.1...34.12) bestehen. Gekennzeichnet ist das Seil durch eine integrierte Frostschutzeinrichtung (33.1...33.6), welche von einem Seilende her bedienbar ist, bevorzugt um Eisbildung an einer Seilaussenseite zu verhindern bzw. gezielt zu entfernen. Die Frostschutzeinrichtung (33.1...33.6) ist dabei bevorzugt in zumindest einer der Aussenlitzen integriert, kann jedoch auch im Bereich des Kerns (31) des Seils oder in Einlagen integriert sein, welche Zwischenräume zwischen einzelnen Drähten (32.1...32.6, 34.1...34.12) des Seils ausfüllen. Da die Frostschutzeinrichtung (33.1...33.6) bevorzugt als Widerstandsheizung ausgebildet ist, lässt sich ihre Heizintensität durch Stromfluss genau einstellen. Durch längs des Seils veränderliche Querschnitte oder veränderliche Materialeigenschaften der Heizdrähte (33.1...33.6) ist es möglich, besonders intensiv zu heizende Abschnitte des Seils konzentriert zu heizen. Auf diese Weise kann der gesamte Energieverbrauch der beschriebenen Vorrichtung möglichst klein gehalten werden. Dabei können unterschiedlichste Konstellationen von Litzendrähten (32.1...32.6, 34.1...34.12), dem Kern (31) des Seils und den Frostschutzeinrichtungen (33.1...33.6) von der Integration der Frostschutzeinrichtungen (33.1...33.6) im Kern (31) des Seils bis zu deren Positionierung auf Teilen der äusseren Oberfläche des Seils auftreten.

It is described a rope, which is particularly suitable as a support cable for cable cars. The cable comprises a core (31) and a plurality of outer strands surrounding the core, which consist for example of a plurality of wires (32.1 ... 32.6, 34.1 ... 34.12). The rope is characterized by an integrated antifreeze device (33.1 ... 33.6), which can be operated from one end of the rope, preferably in order to prevent ice formation on a rope outer side or to deliberately remove it. The antifreeze device (33.1 ... 33.6) is preferably integrated in at least one of the outer strands, but may also be integrated in the region of the core (31) of the cable or in inserts, which intermediate spaces between individual wires (32.1 ... 32.6, 34.1 ... 34.12) of the rope. Since the frost protection device (33.1 ... 33.6) is preferably designed as resistance heating, its heating intensity can be adjusted precisely by current flow. By varying along the rope cross sections or variable material properties of the heating wires (33.1 ... 33.6), it is possible to heat intensively heated sections of the rope concentrated. In this way, the total energy consumption of the device described can be kept as small as possible. Different constellations of stranded wires (32.1 ... 32.6, 34.1 ... 34.12), the core (31) of the cable and the antifreeze devices (33.1 ... 33.6) can be combined with the integration of antifreeze devices (33.1 ... 33.6) in Core (31) of the rope to their positioning on parts of the outer surface of the rope occur.
